Template holders are the heart of an elevator and its a guide for the full installation process. The framework is made according to the measurements in installation drawings. Profiled steel is usually used for high rise lifts while wood is the least used.
Template holders setup
Template holders are fixed in the hoistway 500mm below the floor of the machine room, in a scenario where there is no machine room or there is a small machine room the template holders are fixed in the hoistway 250mm below the top plate of the hoistway.

According to the vertical lift hoistway drawing the ring beams or the embedded steel plates of the hoistway, the positions and exterior dimensions of the ring beams of the hoistway and steel plates of the brackets should be checked.
Landing doors installation
Buffer selection is always in accordance with the speed rate, hydraulic buffer is mostly used.
Safety gears and car frame installation
